Learning Haskell

This portal points to places where you can go if you want to learn Haskell.

The Introduction to Haskell on the Haskell website tells you what Haskell gives you: substantially increased programmer productivity, shorter, clearer, and more maintainable code, fewer errors, higher reliability, a smaller semantic gap between the programmer and the language, shorter lead times. There is an old but still relevant paper about Why Functional Programming Matters (PDF) by John Hughes. More recently, Sebastian Sylvan wrote an article about Why Haskell Matters.
